Description
Technical field
The present invention relates to a kind of rubber and preparation method thereof, particularly relate to a kind of EPDM rubber sponge and preparation method thereof.
Background technology
The making of micropore elastomer material comprise utilize the latex fluid mixture process the sponge foam materials with utilize the organic blowing agent decomposes to process approach such as sponge foam materials.USP No. 3300421 (US Patent 3300421,1967) is disclosed a kind ofly can be used to make the highly elastic a kind of microvoid structure polymer materials of having of gasket material and wrapping material.The described porous structural material of this patent of invention obtains as raw material from latax foam or rubber-like polyurethane foam etc.Japanese Patent Laid is opened the 2002-179825 communique and has been announced a kind of mode of making rubber sponge.This patent of invention is through adding whipping agent in elastomeric material, when making its foaming with the crosslinked EPDM of the manufacturing bipeltate of organo-peroxide.
Known EPT rubber packing material comprises the ethylene-propylene diene copolymer class sizing material that has cooperated organo-peroxide and can form required form and carry out the crosslinked non-rubber sponge that makes.This non-rubber sponge is crosslinked with organo-peroxide, and the bound energy of formed C-C key is bigger than the bound energy of the C-S key that sulfur cross-linking forms, and has improved the sealing property of goods whereby.
The rubber sponge material has that density is little, light weight, thermal insulation and advantage such as sound insulation property is good, compression set is low, is specially adapted to process sealing material.The sealing material that rubber sponge is processed can be applicable to a plurality of fields such as insulation, buffering, vibration damping.In some special use occasions, the hygroscopic property of rubber sponge joint strip is often had higher requirements.Traditional rubber sponge joint strip does not have this function.
Molecular sieve is a kind of aluminosilicate of crystal type, has regular and uniform duct in its crystalline structure, and the aperture is the order of magnitude of molecular size, and this structure makes it have very strong wettability power.Molecular sieve is Powdered crystal, and very big specific surface area is arranged, and reaches 300-1000m
2/ g has metalluster, has reinforcing property preferably, has better strengthening action than the kaolin of homogenous quantities, potter's clay, light calcium carbonate, talcum powder etc.Terpolymer EP rubber molecular backbone chain structure has saturability and kindliness highly completely, not only shows good rebound resilience and lower temperature resistance.After the introducing carbon black is as ultraviolet screening agent, also have multiple performances such as better heat-resisting property, ozone resistance and weather-proof aging, anti-old performance.The low-unsaturation-degree of terpolymer EP rubber helps in sulfidation, forming C-C key and C-S key, when goods are compressed, is difficult for producing tension set.Based on above 2 points, molecular sieve powder is joined in the ethylene propylene diene monomer (EPDM) material as weighting agent, make ethylene-propylene-diene monomer gelatin sponge sealed strip when having moisture absorbing, also have good weather.
